Example 1

Referring to fig. 1 to 12, the trash can of the present embodiment includes: an outer tub 1 and an inner tub 2 fixedly or detachably installed therein;

the garbage can further comprises a can cover 4, the can cover is rotatably arranged on the rear side of the upper end of the inner can, an uncovering support rod 41 is rotatably connected to the position, close to the rotating shaft, of the can cover, and a support rod seat rotatably connected with the uncovering support rod is arranged on the inner side of the can cover; and the uncovering support rod drives the barrel cover to rotate upwards when moving upwards. Furthermore, a limiting part for limiting the rotation range of the barrel cover can be arranged at the connecting position of the inner barrel and the barrel cover, for example, the rotation range of the barrel cover is limited to 0-120 degrees (0 degree is the horizontal state when the barrel cover is closed).

The garbage can further comprises a pedal 3, the pedal is located on the front side of the outer barrel and close to the bottom, the pedal is connected with a pedal support 30, the whole pedal support shown in the figure 2 is of a rectangular frame structure, and the positions, close to the middle, of two sides of the pedal support are rotatably connected with the inner barrel. Specifically, pedal supports 21 are arranged on two sides of the bottom of the inner barrel, rotating rods are connected to the positions, corresponding to the pedal supports, of the pedal supports, and the pedal supports are rotatably connected with the pedal supports through the rotating rods.

It should be noted that, unless otherwise specified, the front side and the rear side are both the rear side corresponding to the side where the tub cover is connected to the inner tub and the front side corresponding to the side where the pedal is located.

As shown in fig. 3 to 5, an end of the pedal bracket away from the pedal is connected to the uncovering brace. The lower end of the uncovering support rod is connected with a long-strip-shaped limiting sliding sleeve 42, and the limiting sliding sleeve is connected with one end, far away from the pedal, of the pedal support in a sliding mode.

As shown in fig. 4, when the pedal moves downwards to the limit position, the barrel cover rotates upwards by more than 90 degrees, and after the pedal is reset, no interaction force exists between the pedal bracket and the limiting sliding sleeve in the vertical direction. Under this kind of state, the bung rotates and exceeds 90 degrees, and the gravity of bung self makes the bung can not automatic re-setting, and the footboard support after resetting in addition does not produce pressure to spacing sliding sleeve, also can not make the bung reset, that is to say that the bung under this kind of state can only the bung manually turn reset, and this action of just having made things convenient for the bag clamp of opening avoids the bung to open the bag clamp and produces the interference.

Further, as shown in fig. 19, the handle holes are designed to be smaller and two side by side, and the size of each handle hole is based on the finger of the ordinary person to pass through.

As shown in fig. 20 and 21, a second welding line 603b is provided in the width direction near the bottom of the disposal bag, and the second welding line forms a raised unlocking portion on one side of the disposal bag, and a second dot-and-dash line 604b is located below the second welding line. Be equipped with on the locking piece with the driven step portion 71b of unblock portion cooperation joint for when the disposal bag was dragged, the unblock portion on the disposal bag can drive the unblock of locking piece.

Example 3

The difference between this embodiment and embodiment 1 is that the structure of the bag box and the garbage bag is modified: specifically, as shown in fig. 22, the bag box of the present embodiment is loaded into the trash can from the front side of the outer barrel, compared with the way of loading from the top of the inner barrel, the way of loading from the front side of the outer barrel avoids the obstruction that may be generated by the bag opening clamp.

Further, as shown in fig. 23 and 24, the container body includes an outer container 61 opened at a side surface thereof and an inner container 62 opened at an upper end thereof, and a plurality of garbage bags connected by a dotted line are mounted in the inner container and stacked in a height direction of the inner container.

A bag channel 63 for the garbage bag to pass through from top to bottom is formed between the outer wall of the inner box close to one side of the outer barrel and the inner wall of the outer box at the adjacent position. Specifically, the inner extending wall 621 is formed on two sides of the outer wall of the inner box near one side of the outer barrel, and the inner extending wall abuts against the inner wall of the outer box, so as to form the bag channel 63. The top of the inner box near one side of the bag channel is provided with a third guide rod 617, and the garbage bag in the inner box enters the bag channel 63 downwards after passing through the upper end of the third guide rod. A bag outlet 64 for the garbage bag to pass through is formed between one side of the side opening of the outer box and the lower end of the inner box. Bag through holes 23 are formed in the front side wall surface of the inner barrel corresponding to the bag outlet and used for garbage bags to penetrate into the inner barrel from outside to inside.

An unlocking shift lever 68 which can drive the locking piece 7 to unlock in the rotating process is rotatably arranged at the position, located at the locking piece extending opening, of the inner bottom of the outer box 61 of the box body. The side wall of the unlocking driving lever is provided with a shifting piece 681 corresponding to the position of the lock catch on the locking piece, and when the unlocking driving lever rotates for one circle, the shifting piece shifts the lock catch once to unlock the locking piece.

A rubber roller 66 is rotatably arranged at the inner lower part of the outer box of the box body, and one outer wall surface of the garbage bag is in transmission connection with the outer wall of the rubber roller through friction force; the rubber roll is in transmission connection with the unlocking deflector rod through a reduction gear set 67, and when the distance for moving the garbage bags is just the length of one garbage bag, the unlocking deflector rod just rotates for a circle. The outer wall surface of the garbage bag in contact with the rubber roller forms the unlocking part.

Furthermore, the outer surface of the rubber roller is fixedly sleeved with a sticky rubber sleeve, so that the garbage bag and the rubber roller can move at the same linear velocity. In order to prevent the garbage bag and the rubber roller from sliding relatively, a contact surface between the garbage bag and the rubber roller is large enough. First deflector roll 661 is still installed to the position that the lower part is higher than rubber roll lower tip in outer box, second deflector roll 662 is still installed to the position that the lower part corresponds out sack 64 in outer box. The garbage bag led out downwards from the bag channel bypasses the lower end of the rubber roller, then bypasses the upper end of the first guide roller, bypasses the lower end of the second guide roller and finally penetrates out of the bag outlet. The first guide roller enables the garbage bag and the rubber roller to have a larger contact surface in the circumferential direction, and meanwhile, the garbage bag and the unlocking deflector rod keep a sufficient distance, so that the pulling piece is prevented from obstructing the dragging of the garbage bag.

The speed reduction gear set 67 comprises a first gear coaxially and fixedly connected with one end of the rubber roll, a fourth gear coaxially and fixedly connected with one end of the unlocking deflector rod, and a second gear and a third gear which are rotatably arranged on the outer side wall of the outer box, wherein the second gear is coaxially and fixedly connected with the third gear, and the number of teeth of the second gear is greater than that of the third gear; the first gear is in meshed transmission connection with the second gear, and the third gear is in meshed transmission connection with the fourth gear.

The difference between the embodiment and the embodiment 1 is mainly that the locking piece is pushed to be unlocked through the matching of the rubber roller and the unlocking deflector rod, and the rubber roller and the garbage bag are transmitted through friction force, so that the mode that the locking piece is directly driven to be unlocked by directly using the hole or the protrusion on the garbage bag in the embodiment 1 is replaced. The quality (mainly toughness, thickness) requirement to the disposal bag of this embodiment is lower, and embodiment 1 then is higher relatively to the requirement of disposal bag, and manufacturer or user can select the sack box according to actual demand, and other parts of garbage bin can be suitable for completely, need not adjust the inner structure of garbage bin, and the suitability is strong.

In addition, because the rubber roller is arranged in the bag sub-box instead of the garbage can in the embodiment, when the bag sub-box is replaced, an ordinary user only needs to penetrate the end part of the garbage bag through the bag perforation on the inner barrel and then install the bag box on the garbage can, the garbage bag does not need to be bypassed around other parts, and the operation is convenient.

On the other hand, because the mounting means of rubber roll for even a little error in the process of dragging the disposal bag, this kind of error also can be eliminated when changing the bag subbox, can not have the excessive accumulation of error and cause the unable normal use condition of garbage bin.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
